Summary

The key source for the principal Internet telephony services and standards.

The Internet now handles extensive video, teleconferencing, fax, and voice communications, in addition to basic data transfer. But overlapping standards for mixed media transmissions can confuse even the most sophisticated engineers. Experienced telecom leader Uyless Black brings together all the tools and protocols for call processing in this single authoritative source.

Internet Telephony begins with an overview of basic telephony call processing, focussing on the differences between traditional circuit switching and the more contemporary packet-based networks. A special section discusses telephony routing over IP. Along the way, Black explores the major standards and protocols in detail. Highlights include:

  • H.323: the ITU standard for transmitting mixed media signals via LANS and WANs
  • SIP: the IETF's Session Initiation Protocol used for IP teleconferencing
  • Megaco Protocol: a combined IETF/ITU standard for multimedia conferencing
  • MGCP: a call processing protocol, published as an informational RFC

For engineers, managers, or users, Internet Telephony is the one book to cover all the technologies.

摘要
《網際網路電話》是主要的網際網路電話服務和標準的關鍵資源。現在，網際網路不僅處理基本的數據傳輸，還處理大量的視頻、視訊會議、傳真和語音通信。然而，混合媒體傳輸的重疊標準可能會讓即使是最複雜的工程師感到困惑。經驗豐富的電信領導者Uyless Black在這本權威的單一資源中匯集了所有的呼叫處理工具和協議。

《網際網路電話》首先概述了基本的電話呼叫處理，重點是傳統的電路交換和更現代的基於封包的網絡之間的差異。一個特別的部分討論了IP上的電話路由。在此過程中，Black詳細探討了主要的標準和協議。重點包括：

- H.323：ITU用於通過局域網和廣域網傳輸混合媒體信號的標準
- SIP：IETF的用於IP視訊會議的會話初始化協議
- Megaco協議：IETF/ITU的用於多媒體會議的結合標準
- MGCP：作為信息性RFC發布的呼叫處理協議

對於工程師、經理或用戶來說，《網際網路電話》是一本涵蓋所有技術的書籍。
